Introduction to olive crushers

Olive crushers are machines designed to crush or grind olives in order to facilitate the extraction of olive oil. They constitute a fundamental piece of equipment in the olive production chain, since they prepare the raw material for the subsequent processes of beating and pressing or centrifuging, where the oil is separated from the rest of the components of the olive.

These shredders can vary in size, design and technology, from manual or semi-automatic models to large automated industrial installations. Its main function is to break the pulp and stone of the olive to release the oleaginous paste that contains the oil, ensuring an efficient process and maintaining the quality of the final product.

Hammer crushers

Hammer crushers are one of the most common types in the olive industry. Its design includes a rotor with multiple hammers that rotate at high speed, impacting the olives against a grid or fixed surface to crush them. This system allows for quick and efficient crushing, suitable for large volumes of olives.

These machines offer a fine and homogeneous crushing, which facilitates the subsequent extraction of the oil. However, the impact of hammers can generate some heat and oxidation, so it is important to control the rotation speed and process time to preserve the quality of the oil.

They are especially useful in olive mills with high production, due to their robustness and ability to process large quantities of olives in a short time.

Disc or grinding wheel crushers

Disc or grindstone crushers are another traditional and highly valued method for crushing olives. They consist of two discs of stone or synthetic material that rotate in opposite directions, crushing and crushing the olive to obtain the oily paste.

This system allows for a softer and more homogeneous crushing, with less heat generation and oxidation compared to hammer crushers, helping to preserve the organoleptic properties of the olive oil.
